Leners Patent No. 90,941, daad Jungs, 1869.
IMPROVEMENT IN BEDSTEADS, SEATS, 8c'c.
m The Schedule referred to in these Lettersv Patent and making part of the same.
To all to whom these presents shall come Be it known that I, CLINTON T. FROST, of Medfield, in the county ofV Norfolk, and State of Massachusetts, have made au invention of a'. new and useful improvement, having reference to beds and various other articles of furniture, land-conveyances, Snc. and do hereby declare the following to be a full, clear, and exact description thereof, due reference being had to the ac companying drawings, making part of this. specification, and in which- 'Figure 1 is a perspective representation, and
Figure 2, a vertical and transverse section, in one form of its manifold adaptations, of my invention.
-Fgure 3 is a representation of a modication of my `invention.
This invention is intended to produce a yielding or buoyant foundation for bed-bottoms, seats to articles of furniture of various kinds, land-conveyances, or vehicles ofvariousdescriptions, 8m., which shall'possess the advantages of cheapness, durability, and ease.
I have embodied, in suchinvention, two cross-frames, the arms of which are pivoted together at their centres, substantiallyater the manner of the old and wellknown cot-bedsteads, so called, except in this, thatY whereas in the cot-bedstead, the upper extremities of the arms are united by longitudinal rails, to which is secured the sacking which forms the bed-bottom, I unite the lower extremities of such arms by longitudinal rails, and dispose, upon the upper and free .ends of such arms, aslatted frame, for supporting the bed and bedding, such slatted frame being secured, at one side, to the arms, and, at the opposite side, resting upon anti-friction rollers, applied to the extremities of the opposite arms, whereby the yielding, or buoyant mot-ions of the bed are greatly enhanced, and ease and comfort of the occupant greatly increased. A
V.A further novel point in this invention consists in the application, to the opposite diverging arms of the two adjacent cross-bars, of springs, so .disposed as to force asunder their extremities, and produce anelastic connection between them, and consequently between the slatted frame, which supports the bedding, and the bedstead, which supports the lower extremities of thecross-bars, the whole being as hereinafter explained.
In the drawings, to which allusion has before been made as accompanying this specification, and which illustrate m invention a a' denote two crossed arms pivoted together at their centre, as shown at B, and having their lower extremities united by longitudinal 'rails c c, such rails, whenV the bed-bottom is in use,
WO Y
being supported upon or within an ordinary bedstead,
after the manner of Various spring-bed bottoms now in extensive use.
Upon the upper, and free extremities of each pair of cross-bars a. a', I dispose a .slatted frame, el, the
`transverse slats e e of which rest directly upon, and
are fixed to the extremities of' one opposite pair of' bars, while the opposite ends of such slats rest upon anti-friction rollers f j, pivoted to the contiguous ends of the opposite bars a an( a. 4
Within the fork, or acute angles formed by the intersection of eachjpairof cross-bars, I apply a spring, of any suitable shape, which is capable of forcing the extremities of the bars asunder, and producing a yielding connection of the same, such springs, in thc present instance, being shown at h, &c. l Y
A device made as above described will be found to constitute a very economical, durable, and luxurious foundation for the'purposcs of bed-bottoms, seats of articles of furniture of various kinds, pleasurc-car riages, 85o,
[I would remark, that in adapting the novel features of my invention to the purposes o fa cot-bedstead, the only change necessary is to change the longitudinal rails from the lower extremities ot' the arms a a to a position about midway between such extremities. and the pivot b, and in applying casters to such extremities,
the connected pairs of arms "being brought intoposition nearer' iight angles to each other, as shown in fig. 3 ofthe accompanying drawings, in order to increase the altitude of the bed-supporting frame or sacking, as the -case may be, from above the surface of the floor.
I am aware that cross-bars with lifting-springs, have been Vbefore used in bed-bottoms, and to this I therefore make no claim; but
W'hat I claim as my invention, and desire to secure by Letters Patent of the United States, i's'-\ -A device for constituting bed-bottoms, spring-seats, I
&c., composed of' the cross-barsa a and a a, pivoted together, and provided with springs, and supporting, upon their upper, and free extremities, the slatted frame d, such frame beingy fixed to one extremity of each arm, and resting upon anti-friction rollers applied to opposite ends thereof, the whole being substantially in manner as before explained. V .y
CLINTON T. FROST.
